What is our observer and how it works?
Observer is a place which stores processes and delivers Web pages to a client's.
What clients is nothing but our browser on our laptops and smartphones?
As you can see in this image.
The communication between client and server takes place using a special protocol called Hypertext Transfer
Protocol, which basically HDTV.
I think that you are familiar with this one because you see it in almost all length and all pages in
this protocol, the client here.
Initiates communication by making a request for a specific Web page using ECB protocol, and the server
then responds with the content of that Web page or an error message if it was unable to do that, like
the famous 404 error page, pages delivered by a server are mostly assembled documents or PSP documents.
Now, let's take a quick example.
This browser is our client now free, right?
Google dot com.
It will provide HDTV, which we already mentioned, and it will ask the server to deliver this Web page,
which is Google dot com.
Now, this request will go from the old client, which is this browser to Google servers and Google
servers will respond with this page content, which is basically an image and two buttons.
So this is us communicating with Google server using our old client, which is this browser.
I think now that this idea is more clear and we are going to transfer our PSP board to our Web server
and we are going to write an e-mail code so that whenever someone sent a request to our export server,
it will respond with the pages that we did create inside it.
Thanks for watching this lesson.
